Lpc826 - lpc 815 - phr803t - sfaw210 - ggwh20l - bdr-s06j

I'm up for two LPC826's. I've got a few Aixiz mounts I want to fill ;)

My 4 arrived today; thanks!

Hey Laserwinkel;

I've sent you two PM's in the past 10 days and have yet to get a reply from you. I'm interested in some of the LPC-826's if you have any left. Please reply with shipping costs to the US (postal code 29418). Thanks.

Adam

I have sent pm few weeks ago , but there is not answer :)
What's price of one lpc826 shipped in country Georgia?an is it stil available?

Has anyone tested the robustness of the LPC826's yet? There may have been some improvements there making them a little harder to kill.

If they turn out to be anywhere near as indestructible as the 445nm diodes, I'm pretty happy with it.

I have had one running for over 24 hours now @ 550mA, cooled to 20c. So far so good.

Please Keep us posted... What's the output at 550mA?

With an Axiz 660nm AR lens, 267mW @550mA. - EDIT: My LPM batteries went flat, this reading is not accurate, see later post with graph.

I have another 7 LPC-826 diodes here, I will batch test them all over this Easter weekend. Tonight I will be pulling my quad apart for a more compact rebuild, so will test 815 and 826 side by side with a Flexmod P3 on each. I'll establish lasing threshold and will also plot power vs current for both on the one graph.

Well I just randomly pulled an 815 and an 826 out of my supply and sent both thru a kill test. Simple hookup at an ambient of 24C° passive heat sinking with Dave’s mounts measuring raw power while upping the power to the kill point. Unfortunately I can’t plot current and power at the same time.

As in previous tests the 826 died at exactly 650mA outputting 440mW (see chart).

Now here it comes, the 815 diode doesn’t want to die (see chart):confused:. It peaked out at 870mA outputting 503mW. Further current increase (up to 1000mA) resulted in continuous power drop. I turned the power down and ramped up again with the same results. I let the diode live due to extraordinary performance. This behavior has been observed with the 822 diode but with not near the power output.

I suspect there may even be differences in diodes used in the 815 sleds, there are also 2 different diode mounts used in these sleds.

Ok, I have now compared LPC-815 with LPC-826 with the following setup:

Dave's Brass LD mounts on a 3x4" aluminum base.
Axiz 660nm AR glass lens.
Flexmod P3 driver.
GW Instek GDM-8245 50000 count 0.03% accuracy bench DMM.
Radiant Alpha LPM.

The slope is steeper, and the output continues to climb after the LPC-815 drops off.
